From where?
Glastonbury is in Somerset, England. It is not in Scotland.
Assuming a small dinghy like Finn Class can develop speed up to 5 knots (let's say 10kph) and a rough distance form Norway shore to Scotland shore is about 500km, I'd say about 50 hours, so maybe 2 days?

depends on where your coming from...
That depends on where you are travelling from.
You can be in Scotland from Dublin by air in less than 40 minutes.
There is no direct train from Paris to Scotland. One option is to take a train from Paris to London, and then take another train from London to Scotland. The total travel time can range from around 7 to 11 hours depending on the connections and routes chosen.
Scotland is a big place but from Edinburgh, 8-9 hours.
